I have a mid 2010 Macbook Pro, see specs below in my signature. I have had it apart a few times... to clean, upgrade the ram, and to replace the HDD with an SSD drive. I was thinking about when i used to have desktops and remembered that the thermal paste always got bad after a few years. Does anyone clean and replace their thermal paste in their macbook pro's? Is this something worth doing or just a waste? I have not looked, but i am sure its all hard and gunked up. if i should of done this already, please post tutorial if you have one.
